2. solve quadratic equation that formed.
Answer: 1.25
Step-by-step explanation:
because it is
Answer: -4
Step-by-step explanation:
3-2(0-4)
Do the parenthesis first
( 0 - 4 )
( -4 )
Then solve the other equation
3 - 2 = 1
put them back in order
1(-4)
Now solve for that and you have your answer
-4
Answer:
-1
Step-by-step explanation:
If a straight line passes through the known points (x1, y1) and (x2, y2), the its slope is given by
Now, in our case the straight line passes through the points (1.8, - 3.4) and (6.8, - 8.4).
Therefore, the slope of the required straight line will be
